For the eighth installment in the 'Know your Soils' series from the Sectormentor for Soils team they share the three easiest and key soil tests to do on your land. The infiltration rate test, earthworm test and slake test require basic equipment which can be found on most farms. They will give you a good idea of your soil structure, organic matter content, and how much biological activity is happening - all of which are key for healthy soil. All the 'Know your Soils' resources share practical tips for monitoring soil health and simple tests you can do on your land.

Findings & recommendations:

Clever land management can contribute to building soil health - reducing top soil run-off and nutrient leaching.

Healthy soil has an aggregated or crumb structure created by biological activity - true aggregates will not break down in water, aggregates formed from compaction will break down in water.

Earthworm counts can help indicate the level of biological activity in the soil - earthworms are the largest organisms in the soil food web.

There are three types of earthworm you can find in your soil: litter feeders break down organic matter on the surface, topsoil worms work on soil aggregation and nutrient mobilisation, deep burrowers keep water percolating deep down.

The infiltration rate test shows how well your soil can take in and hold water.
